Investigating the Mechanical Properties of FCC Structured Material Processed by Equal Channel Angular Extrusion

摘要

Severe plastic deformation (SPD) process like Equal Channel Angular Extrusion (ECAE) has involved a large amount of interest, because of its capability to make ultrafine grained microstructures. Equal Channel Angular Extrusion is an inventive method capable of producing homogeneous plastic deformation for a variety of materials with no major changes in geometrical shape and cross section. In the present work pure aluminum has been investigated for ECAE processing. Single pass Pressings were conducted on Al at the room temperature. Experiments were performed by means of ECAE die with channel angle of 120° attached to hydraulic press, moreover Mechanical and micro-structural characterization of the ECA pressed Aluminum is carried out.
